UNITED STATES THOMAS MGGRORY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR'OF ONE- PATENT OFF CE.

HALE TO HOWARD BANES, OF SAME PLACE.

COOLING AND VENTILATING HOUSES.

SPECIFICATION forming part of Letters Patent No. 253,740, dated February14, 1882.

Application filed August 16, 1881. (No model.)

' To all whom it may concern:

Be it known that-I, THOMAS MoGRoRY, of Philadelphia, in the county ofPhiladelphia, and in the State of Pennsylvania, have invented certainnew and useful Improvements in Ventilators'for Houses; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing, and to theletters of IOJGfBI'GDGB marked thereon, making a part of thisspecification.

The object of my invention is mainly to provide certain novel meanswhereby the steam pipes or hot-air fines used for conveying steam or hotair to rooms for the purpose of warming them are practically utilizedfor conveying cool air to the rooms during warm weather.

The following description of my invention, when taken in connecion withthe annexed 2o drawing, will enable others skilled in the art to fullyunderstand it.

The annexed drawing represents avertieal section of a building, showingmy apparatus applied in the cellar and two apartments above 2 5 theground-floor.

Adesignates an apparatus ofany well-known kind adapted for thegenerating of steam, or, if desired,for heating air; and B is thesmokeflue, which leads off from the furnace of the 0 heater into achimney.

O designates a pipe for conveying steam to the radiating-pipe D,arranged in the apartment E, and which also communicates withaperforated outlet-plate register, F, located in 5 the apartment E,whichregisterisdesigned for the supply of cold air to this apartment. Tosupply steam to the radiator D, valves to b are shut and valve cisopened.

G designatesa rotary blower, which may be 40 driven by means of asteam-engine, H, or by means of a rotary engine, I, actuated bywaterpower; or any otherprime motor which is found most convenient andeconomical may be adopted for giving motion to the said blower. The airfor supplying the blower G is preferably taken into a pipe, 'J, from apoint at or near the top of the building, which pipe leads down throughthe building-walls. and enters the suction side of the blower.

If it is designed to reduce the air to a very low degree of temperature,I adopt the followin g contrivance K designates a receiver for ice orother refrigerating material, into which dips a worm,

d, of pipe, one end of which worm-pipe com municates with the air-pipeJabove a valve, L, and the other end, 01, of the worm-pipe communicateswith air-pipe J below the valve L. By closing the valve L all of the airwhich is drawn into pipe J will pass through the refrigerator.

It will be seen that the temperature of the air can be regulated. byopening valve L' more or less.

The blower Gr discharges the cool -air into the pipe 0 through a pipe N,and pipe Goonveys the cool air into the apartments E E, and dischargesit equably through the perforated pipe P in apartment E and through theregister F in the apartment E.

The valve a. at one end of pipe P is opened foradmittingcold air intothe apartmentE, and the valve 7) is opened to allow air to pass throughregister F into apartment E.

It will be seen from the above description that I simply combine my 'airforcing and cooling apparatus with the ordinary steam-heating pipescommonly used in buildings, and add to such pipes certain regulating andcut-off valves.

It is obvious that the air might be purified and filtered by the use ofsuitable means applied for this purpose.

I do not claim the apparatus nor any part of the apparatus shown anddescribed in the Letters Patent No. 51,236 of November 28, 1865.

I claim as my invention 1. The combination of the steani-heate thecooler, the air-inlet pipe L, the forcingengine, pipes O N, valves a b0, radiator D, and the perforated pipe P, substantially as described.

2. The combination of a radiator, D, the perforated pipe 1?, and valvesa c, substantially as and for the purpose described.

In testimony whereof I affix my signature,

in presence of two witnesses, this 28th 'day of July, 1881.

THOS. MOGRORY.

T. J. OoYE, WM. M. MCKNIGHT.
